Post-quantum Secure Cryptographic Algorithms

Konstantin Nikolaevich Pankov, Михаил Михайлович Глухов

This paper assesses cryptographic security for new, Fourth Industrial Revolution technologies against quantumenabled risks. In this context, the history of successful attacks on post-quantum cryptography algorithms is reviewed and a thorough cryptographic study of these algorithms' resistance to various cryptographic analysis methods is proposed. The paper also describes an effective attack on a post-quantum algorithm proposed by the authors in earlier studies. This description concludes that using the previously proposed parameters is insecure. Modifying these parameters necessitates further investigation into the cryptographic strength of the post-quantum algorithm.

One of the modern directions in the field of information security is post-quantum cryptography. Its purpose is to develop new quantum-resistant cryptographic algorithms. An important section of post-quantum cryptography is electronic digital signature algorithms. There are a number of different approaches to designing post-quantum signatures. One of the main approaches to designing post-quantum cryptographic digital signature algorithms is hash-based post-quantum digital signature schemes. Hash-based post-quantum digital signature schemes are one of the main types of post-quantum cryptographic digital signature algorithms. They are quite efficient and provably secure. Their reliable security has been established against both classical and quantum attacks. There are many types of digital signatures for solving various information security problems, such as group signatures, ring signatures, blind signatures, verifiably encrypted signatures, etc. This paper proposes a new cryptographic protocol of verifiably encrypted signature with possibility of verification after a specified time based on the post-quantum cryptographic algorithm of hash-based digital signature, TANBA-SPHINCS+. The protocol is an efficient combination of the postquantum digital signature algorithm TANBA-SPHINCS+, the cryptographic protocol providing data encryption for a specified time, ECTLC, and the verifiably encrypted signature scheme.

The emergence of quantum computing presents a significant challenge to traditional cryptographic methods, particularly in network security. Post-quantum cryptography (PQC) has emerged as a potential solution to secure digital communications against quantum-based threats. This article provides a comprehensive overview of PQC algorithms and their role in strengthening network security. We discuss the limitations of current cryptographic systems in the face of quantum algorithms, such as Shor’s and Grover’s algorithms, which threaten the security of widely-used protocols like RSA and ECC. We explore the major families of PQC algorithms, including lattice-based, code-based, and hash-based approaches. This article also evaluates the practical challenges of implementing PQC solutions and the future direction of cryptography in the post-quantum era.
